Anybody used the 1999 or newer hydroboost on the 97 and older trucks. I know the newer ones are all metric but it seems the older 450 units are impossible to find or really expensive while the newer ones are everywhere and cheaper. I don't know for sure but it should just be a matter of getting the right hydraulic adapter to go from the metric to sae and enlarging a few holes with a drill. Even if it's a more difficult swap id rather do it for the ease of finding replacements and parts. So if anyone has done the swap I would like to know the details.
